what Apple’s A5 processor looks like? The brain behind the iPad 2 and
the upcoming iPhone 5, the A5 system-on-a-chip combines a dual-core
processor and PowerVR GPU to deliver improved performance over the 2010 model. Chipworks
disassembled an iPad and put the A5 under a microscope to eyeball all
of the changes between the two Apple processors. With its dual-core ARM
Cortex-A9 processor, the A5 is more than double the size of its
predecessor, measuring 10.1mm x 12.1mm compared to the A4’s 7.3mm x
The Apple A4 SoC.
Apple's A5, which is actually twice the size of the A4. Two cores!
Chipworks noted the similar design of the A4 (left) and A5 (right) and deduced that Samsung is still fabricating Apple's chips.
